Dataframe write gives error in createRelation method

Hi,
I am trying to write dataframe to a file and getting following exception.

java.lang.AbstractMethodError: com.crealytics.spark.excel.DefaultSource.createRelation(Lorg/apache/spark/sql/SQLContext;Lorg/apache/spark/sql/SaveMode;Lscala/collection/immutable/Map;Lorg/apache/spark/sql/DataFrame;)Lorg/apache/spark/sql/sources/BaseRelation;

Which Spark version are you using? Sounds like a version incompatibility.

Hi,
I am using Spark 1.6.

Thanks,

Spark < 2.0 is actually not tested and your example seems to indicate that it's actually not working anymore.
I'll update the README accordingly.
Are you able to update to Spark >= 2.0?
We're using Spark >= 2.0, so we won't invest time in maintaining older versions.
If you absolutely need that, you'd need to create a PR with the required changes.
